It is called echolocation.
ECHOLOCATION SONAR
Hearing, music, telephones, and vacuums are examples of sound energy.
use a scale to find the mass
Ultrasounds are those sound waves that have a frequency that is higher than human hearing range that is above 20000 Hz. Bats produce these kinds of sound waves when they fly, this sound wave hits any obstacle(prey or enemy) in its path and gets reflected back to the bat (bcoz angle of incidence is always equal to angle of reflection). The bat senses the time taken for the sound wave to return and judges the distance of its prey or enemy. this help it to find its prey or enemy. Bats have this kind of adaptation because they donot have eyesight.

ECHOLOCATION SONAR
SONAR (sound navigation and ranging)
Disk-winged bats use echolocation to find their prey. The bat uses a high pitched sound that is reflected off of objects in its surroundings.
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
Whut?
Objects by sound. Mostly in water
ultra sound echo bounces back from objects and the distance of the obstacle can be calculated from the speed of sound that travels at 340 mt /sec . Missing objects in water or any open place can be located by sending an ultra sound wave and receiving it on any radio receiver.
it seems humans use echolocation to find certain specific things they really need or objects and mainly sound
Bats and dolphins find their food and navigate through a sensory system called echolocation.Echolocation is a physiological process for locating distant or invisible objects (such as prey) by emitting sound waves that are reflected back to the emitter by the objects. It is used by an animal to orient itself, avoid obstacles, find food, and interact socially.
An echo is like a sonar because they both reflct the sound they cause. The sonar is useful to the navy army to find out where the lost ships are located, so basically they are navigating the exact location of ships and sumbarines. An echo as you can see can be most used when screaming in the gym or an enormous place with no one in there. I hope this helped you.
Sonar (or Sound Navigation and Ranging) is a type of technology that was designed to help with navigation, communication and locate objects underwater. Sonar projects sound waves then listens for the echo of the emitted sound waves to detect objects.
Sonar (SOund NAvigation and Ranging) is used to find objects. Sonar is used to find ships, submarines, mines, and other objects in the Navy. Sonar is used in Medicine to find unusual tumors, organs, and cells. Sonar is used in Geology to find minerals, oil, rock formationsn, and water .
